AbstractOvariectomy has been used to study the role of the ovary in endocrine homeostasis. Our studies on young virgin adults of the cockroach Blattella germanica (L.) (Dictyoptera, Blattellidae) show that the cytological development of the corpora allata (CA) in ovariectomized females proceeds as in intact specimens, whereas the rates of Juvenile Hormone (JH) synthesis are lower. Stimulation of the CA from ovariectomized females in vitro by mevalonolactone suggests that enzymatic mechanisms which follow mevalonate formation in the biosynthetic pathway are functional. The synthetic capabilities of these CA are also illustrated by the kinetics of JH production in vitro, because hormonal release increases with time to reach 'normal' levels after 8h of incubation. Our data suggest that the absence of ovaries leads to effective inhibition of JH biosynthesis rather than to an impairment of the developmental process in the CA cells.
